Re: Primeval rain forest?
"Depending on the forest, this may take anywhere from a century to several millennia. Hardwood forests of the eastern United States can develop old-growth characteristics in one or two generations of trees, or 150–500 years. In British Columbia, Canada, old growth is defined as 120 to 140 years of age in the interior of the province where fire is a frequent and natural occurrence. In British Columbia’s coastal rainforests, old growth is defined as trees more than 250 years, with some trees reaching more than 1,000 years of age. In Australia, eucalypt trees rarely exceed 350 years of age due to frequent fire disturbance.
Yeah, yeah, I know. It's wikipedia...."
Well, since we're trusting Wikipedia:
'The Huon Pine is a conifer, endemic to Tasmania, and the only member of the genus Lagarostrobos. It is Australia’s oldest living tree species and one of the oldest |living organisms on earth. Individuals have been known to reach an age of 3,000 years.'
Australia is quite a big place, with quite a few different tree species, not just gum trees.
